I take one large zucchini - (at least 8 - 10 inches long), cut it in half lengthwise, spoon out the seeds, and then stuff it with my meatloaf mixture - then bake. It is delicious, covered with marinara, and then mozerella cheese. when you slice it, you have a half moon shaped zucchini slice, with meatloaf, and cheese. Pour some of the extra sauce over it.
I suppose you could use smaller ones for individual servings, too!
I love Zucchinis, baked sliced into salads, fried in butter and added to about any dish you name. I had a great garden a while back and learned the lesson, plant only ONE zucchini plant. I was foolish and planted five! We supplied the local food shelf, several restaurants, a local commune, all the family, way too many neighbors and still had them left over! I have learned and now I deal with them most carefully!!!
My youngest son (now divorced) but his wife was Italian and she made an Italian Baked Zucchini and I can’t remember how she did it but it was mighty delicious and I remember it had a lot of Mozzarella cheese in it or on it (probably both) and the sauce of some kind (probably marinara). I bet the dish you told us about would be wonderful!
I think of her often. She and I got along really well! But she had one hot temper!
